It seems to be an eternal process: new webserver which takes not 50
microseconds, but 10 of them per request and is 5 times faster becomes
the same mochiweb when it reaches it by functionality.

And now I can tell, that there are some features, that are much more
important that exact number of _micro_seconds per request: it is
memory leakage.

i can only agree to that. stability and functionalities [the ones you need!]
are the most important part of all.

it is quite normal that a library slows down as features get added, such as
limiting the data that malicious client can send, etc.

I say slightly slower because the last time I benchmarked it against
misultin, it only differed by a few percent. For most purposes, this
is an irrelevant difference.

i slightly disagree on this, since these are my latest tests with jmeter
comparing mochiweb 1.5.2 tag with misultin master tree [convention is name
of library / concurrent threads], over a simple echoing of a variable passed
in GET:

however, as i've always said, mochiweb is a wonderful library which as a
proven and successful history in running in production. misultin is used in
production too, but i wouldn't be surprised that it is less stable.

i've spent much less time in optimizing speed than in putting efforts to
functionalities and such. there's a perfectly good reason for that. :)
